Hi @Kamal_Chandra,

never give anything as implicit, SonarSource supports \> 20 languages and there are tens of plugins available in the marketplace.

> It seems like the case for me. So locally I have master checked out in 2 locations and I am using the same cache path for both analysis. There are no hits between them when switching from one to another. Note: It is exact same source code. And if I work on one workspace I get 100% hit.

The cache depends on the absolute path too, checkouts at different paths are not supposed to use the same cache. Even more, cache should not be uses for parallel analysis.

You should look at having a stable checkout path, i.e. on `/tmp`.

> I use sonar.branch.name for all my build types and use the same cache for all build type on Jenkins. When I say build type I mean master, branch build and pull requests. ie. on Jenkins master build sonar.branch.name=master and for PR sonar.branch.name=PR-123 and branch build sonar.branch.name=branchname. Is this the way to do it to share the cache across from master to PR to branch builds?

Having only master build updating cache and PRs copying it from master without using it is a good solution. (You may be interested by this topic [SonarCFamily Cache Question](https://community.sonarsource.com/t/sonarcfamily-cache-question/21288))
